Phil talks about syphilis after discovering soap:
“The fight against syphilis and its pacemaker, prostitu-
tion, is one of the most colossal tasks of mankind, colossal
for the reason that it does not involve the solution of a
single question in itself, but rather the abolition of quite
a series of evils which, as their consecutive symptoms,
give the cause for this disease. For the illness of the body
is here only the result of an illness of moral, social, and
racial instincts.” - Mein Kampf
